“…SO 2 diffusion tube monitoring at other volcanoes Diffusion tube monitoring has been undertaken in the areas surrounding Piton de La Fournaise Volcano on Reunion Island, including a network of 26 ground-based SO 2 passive diffusion tubes (Bhugwant et al 2011). Bhugwant et al (2009) highlighted the potential that results from these passive SO 2 diffusion tube have for assisting decision-makers during future eruptions.…”

Sulphur dioxide (SO2) diffusion tube monitoring has been undertaken on Montserrat since 1995, providing a unique and insightful long-term dataset of ground-level SO2 concentrations during the eruption of the Soufrière Hills Volcano (SHV). The monitoring of ground-level SO2 is important to assess the potential of human exposure to high levels of SO2 that may impact on health. Air-quality objectives for SO2 are present in some countries to prevent potential health impacts. Here we summarise diffusion tube monitoring in Montserrat and analyse concentrations with respect to the potential for exposure to levels above recommended levels. We explore relationships that may exist with SO2 flux measurements and volcanic events. Concentrations have been higher during pauses in lava extrusion. Diffusion tube concentrations are highest within 5 km of the volcano and at locations downwind of the plume. Areas where concentrations have exceeded relevant limits have been uninhabited since 1996. The potential for human exposure above recommended limits is, therefore, currently considered low, as the population would not have been exposed to high concentrations for extended periods of time. Full-time occupation and/or long-term exposure in the areas where concentrations exceed the relevant limits would not be advised.
